401k Calculator & Guide
Your age can affect how much you are allowed to contribute to a 401(k). Explore the 2026 regular limit, age 50+ catch-up contribution and the enhanced limit available during ages 60–63.
The basic employee contribution limit does not automatically increase every time you get older. Instead, federal rules provide additional catch-up contribution room once you reach certain ages.
The regular 2026 employee elective-deferral limit applies.
$24,500 regular limit plus an $8,000 catch-up amount, if permitted by the plan.
$24,500 regular limit plus the enhanced $11,250 catch-up amount for 2026.
The general $8,000 catch-up limit applies in 2026 once the enhanced 60–63 window has passed.
The 2026 federal rules create three main contribution stages for most traditional and safe-harbor 401(k) plans.
Regular $24,500 employee limit.
General $8,000 catch-up becomes available.
General catch-up limit remains $8,000 in 2026.
2026 catch-up limit increases to $11,250.
General $8,000 catch-up applies in 2026.
The table below shows the regular employee deferral and applicable catch-up amount for 2026.
| Age during 2026 | Regular employee limit | Catch-up limit | Potential employee total | Rule |
|---|---|---|---|---|
| Under 50 | $24,500 | $0 | $24,500 | Regular limit |
| 50–59 | $24,500 | $8,000 | $32,500 | General catch-up |
| 60–63 | $24,500 | $11,250 | $35,750 | Enhanced catch-up |
| 64+ | $24,500 | $8,000 | $32,500 | General catch-up |
These are 2026 federal limits for most applicable 401(k) plans. Plan terms can impose lower limits or additional restrictions.

Your age qualifies for the standard catch-up contribution.
The catch-up provision gives eligible participants additional employee salary-deferral capacity above the regular limit.
Participants who are age 50 or older by the end of the calendar year can generally make additional elective deferrals if the plan permits catch-up contributions.
SECURE 2.0 created a higher catch-up limit for participants who attain age 60, 61, 62 or 63 during the applicable year. For 2026, that enhanced limit is $11,250.
IRS guidance generally treats a participant as age 50 for catch-up purposes during the calendar year in which the participant turns 50. Similar age-based rules apply to the enhanced 60–63 catch-up provision. Your plan's applicable plan year and rules should still be checked.
These examples show how the 2026 federal limits interact with age. They are not contribution recommendations.
A participant age 35 is below the catch-up eligibility threshold.
Maximum regular employee elective deferral for 2026, subject to plan terms.
A participant age 52 can generally use the standard catch-up provision if the plan permits it.
$24,500 regular limit plus $8,000 catch-up.
A participant who attains age 61 during 2026 falls within the enhanced 60–63 catch-up range.
$24,500 regular limit plus $11,250 catch-up.
The enhanced 60–63 catch-up window has passed, but an eligible participant may generally use the standard age 50+ catch-up amount.
$24,500 regular limit plus $8,000 catch-up.
Age determines catch-up eligibility, while a separate wage rule can determine whether applicable catch-up contributions must be made on a Roth basis.
Beginning in 2026, certain catch-up-eligible participants whose prior-year wages from the employer sponsoring the plan exceeded $150,000 are subject to the applicable Roth catch-up requirement.
A participant may therefore have catch-up eligibility based on age while also having a separate tax-treatment requirement based on prior-year wages.
A 401(k) has more than one contribution limit. Employer contributions and employee deferrals can be subject to the overall annual-additions rules.
The regular 2026 employee deferral limit before applicable catch-up contributions.

Additional 2026 catch-up amount for participants who attain age 60–63 during the year.

Federal limits are only one part of determining what your specific 401(k) plan allows.
Determine whether you are under 50, 50+, or within the enhanced 60–63 catch-up window.
Your payroll records can show how much of your employee deferral limit you have already used.
Your plan may impose lower contribution limits or have specific catch-up provisions.
Certain higher-paid catch-up-eligible participants may be subject to the 2026 Roth catch-up rule.
